    • Chemicals & Materials

      Particle characterization is often a daily routine for businesses related to drilling mud, injection water, sediments and field exploration. Many petrochemical products, such as purified terephthalic acid (PTA) and other polymeric products such as latexes often have particle size distribution as one of the quality control parameters. Laser diffraction, both wet and dry analyses are widely used in these fields and the Coulter principle is the standard method for oilfield injection water analysis. For small organic and inorganic particles dynamic light scattering is one of the widely used methods.

    • Food & Beverage

      Particles in the food and beverage industries are in the forms of powders, emulsions or suspensions. The properties of food and beverage, such as flavor and taste, texture, appearance, color, stability, shelf life, and rheological properties are greatly influenced by particulates in the products, especially their size distribution and surface charge.

      For examples, the particle size distribution affects the dustiness and transport properties of dry powders and the sensorial properties of ice creams, chocolates, ketchup, and etc; the shelf life of baby food is determined by the zeta potential of food particles. Particle size analysis is also very important to size reduction processes of foodstuff such as milk homogenization and flour milling. Sizing can be carried out by dynamic light scattering, laser diffraction or the Coulter principle and zeta potential can be determined by electrophoretic light scattering.

    • Oil & Gas

      In petroleum industry particle characterization is often a daily routine for businesses related to drilling mud, injection water, sediments, and field exploration. Many petrochemical products, such as purified terephthalic acid (PTA) and other polymeric products such as latexes often have particle size distribution as one of the quality control parameters. Laser diffraction, both wet and dry analyses are widely used in these fields and the Coulter principle is the standard method for oilfield injection water analysis. For small organic and inorganic particles dynamic light scattering is one of the widely used methods.

      HIAC™ liquid particle counters are specifically designed to meet the needs of oil analysis customers. HIAC liquid particle counters exceed ISO 11171 for accuracy and reliability. HIAC liquid particle counters are the industry standard for particulate oil analysis.

    • Abrasives

      An abrasive is used to polish or remove excess material from a surface by rubbing it against the surface material. For effective polishing, abrasive particles need to be harder than the surface material. Abrasives are also used in grinding, cutting, drilling, sanding etc. The abrasive particle size distribution is critical in surface smoothness and material removal rate. Agglomeration is a common phenomenon in abrasives. A narrow particle size distribution is preferred because smaller particles lead to agglomerates. These agglomerates may damage the material surface by scratching. The abrasive particle size distributions are traditionally measured using sieves and sedimentation methods. Laser diffraction, an alternate method has gained popularity in abrasive industry for being simple, robust, reproducible and producing faster results. The Coulter principle is also used for counting and sizing abrasive particles with precise particle size distributions.

    • Cements

      Particle size affects strength, development, transportation, quality and drying time of cement powders. Laser diffraction has emerged as the new sizing method in cement industry and competes with traditional methods. Current laser diffraction users in cement industry use both wet (alcohol) and dry laser diffraction analysis. Both methods, depending on their preference produce results that are in excellent agreement with each other. Another method to asses the strength of cement is by measuring the surface area. Gas sorption (both adsorption and desorption) at the clean surface of cement is the most popular method for determining their surface area and powders pore size distribution.

      There are many stages in cement production that need size characterization. Figure 1 shows a typical cement production process. The most important size measurement is for the final product. The largest contribution to cement strength comes from particles smaller than 30µm,while particles smaller than 10µm contribute to the early stage and 10-30µm contributes to the later stage in the hardening process. Generally speaking, the more particles between 3-30µm, the better the cement quality is. The industry generally favors the size distributions where 60-70% of particles are in the range of 3-32µm and 10%-20% are smaller than 3µm. In the grinding process, over grinding will be at high costs and yield too many particles smaller than 3µm that in turn will produce too much heat during solidification, too fast sedimenting, and too many cracks. On the other hand, under grinding will result in too many larger particles that in turn will prolong solidification time and reduce strength.

    • Cosmetics

      Cosmetics are available in a variety of suspensions such as emulsions, gels, lotions, suspensions or creams containing particles. The particle size in cosmetics determines the overall functionality, stability and skin feel. The particle size distributions of both dry and liquid cosmetics are determined using laser diffraction. The stability of a cosmetic formulation depends on the magnitude of zeta potential, measured using electrophoretic light scattering. The Coulter principle is an alternative method used for counting and sizing particles in cosmetics.

    • Mining & Minerals

      Minerals are used as abrasives, as raw materials for other processed products such as cements, or just simply as components for mixtures. Size distribution of mineral dry powders or powders in suspension is very important in monitoring milling processes and quality controlling final products. Laser diffraction has in large extend during the past decades replaced sieving as well as sedimentation analysis for mineral size analysis. The tornado dry powder dispersing technology enables dry analyses of many powders that previously have to be analyzed in non-aqueous environment. For powders having a precise size distribution, the Coulter principle is the golden industry standard. Ores are separated by grinding, mixing with a collector, suspending and floatation. The efficiency depends on adsorption between the collector and the mineral that can be controlled by adjusting surface charge of the particles. The surface charge can be determined by electrophoretic light scattering.

    • Nanotechnology

      Nanotechnology is an emerging field that is rapidly transforming many industries as scientists and engineers develop new ways of designing materials on the nanometer (1 x10-9 m) scale.  Particles such as quantum dots, gold nanoparticles, carbon nanotubes, dendrimers, polymers, micelles, and metallic nanoparticles are being applied in fields as diverse as medicine, cosmetics, food and beverage, and even clothing.  Nanoparticles are attractive because their small size often endows them with special properties not available in the materials bulk state.  For example, quantum dots fluorescent colors are a function of the particle diameter and composition, while carbon nanotubes can adopt a wide variety of mechanical properties depending on their dimensions.  The emergence of nanotechnology has driven the development of new tools for characterization of these tiny systems.  Two of the most reliable and well accepted methods are dynamic light scattering and electrophoretic light scattering, commonly refered to as zeta potential.  Another tool that has produced valuable insights in the field of protein science, but has also been used for quantum dot and carbon nanotube development is the analytical ultracentrifuge, which provides high resolution native conditions analysis.  Beckman Coulter has been a leader in the field of nanoparticle characterization since the introduction of the first dynamic light scattering systems in the early 1980s.  Our history of innovation and world-class expertise continues to be embodied in our nanoparticle characterization products.

    • Toners & Ink

      The print resolution of a toner or ink depends on the size and size distribution of particles in it. The stability of a toner or ink dispersion depends on the magnitude of zeta potential. A low zeta potential may result in agglomeration of toner or ink particles leading to overall poor print quality. Laser diffraction is used to determine the particle size distributions of toners or inks, in both dry and wet forms as it has several advantages: it requires little sample preparation and has short analysis time. The ASTM standard test method F577 describes how the Coulter principle is used for counting and sizing particles in toners or inks. This principle is very useful in providing particle count information above or below a specific size range of interest. One of the parameter that affects charge on the toner particle on a carrier is the total toner surface area. Gas sorption (both adsorption and desorption) at the clean surface of powder inks or toners is the most popular method for determining the surface area of these powders as well as the pore size distribution of porous materials.

    • Water Quality

      Counting and sizing particles in water allows water treatment plants to monitor and optimize their processes. One goal of any drinking water plant is to yield a finished product free of solid particles; therefore it is very important to select a highly sensitive method for testing the final product. The Coulter principle has been used for many years for counting and sizing particles in water. From ultra-clean waters for the semiconductor industry to sediments in murky waters for evaluating filtration efficiency, the use of the COULTER COUNTER analyzers provides a fast, easy, accurate and automatic method to count and size particles. Each and every particle in a sample is analyzed and counted individually giving the technique high sensitivity. The use of electric current reduces variances when compared to other methods. Typical CV’s are less than 2%.
